Interesting lighting, but I think it blows out the glass too much. It messes with the clean lines that would have been a beautiful contrast to the soft glow surrounding the hand. Brilliant idea, though.
This is a nice style and the soft focus strangely works well. I think it's because of the background which is made more interesting by the refractions. The only change I can think would work well is if there was some cognac or something in the glass.
